This week, Julian Scadden explains how the organization he runs, Nexstar Network, helps the owners of plumbing, HVAC, and electrical firms become better business owners. Along the way, he discusses the challenges home-service businesses are confronting, why Nexstar is member-owned (and what that means), and an intriguing decision he made recently to part ways with the 30 percent of his members who are private-equity backed. Those members represented half the organization’s revenue at the time of the decision. I also ask Julian which is the better path: learning a trade and building a business or buying a business and figuring out the trade.
